Description

Technical Field

[0001] This utility model relates to the field of automation control and measurement technology, specifically a multi-axis positioning mounting bracket for encoders. Background Technology

[0002] In the field of automation control and measurement, encoders serve as critical position detection and signal feedback components. The stability and ease of their installation directly impact the operational accuracy and maintenance efficiency of the equipment. Multi-axis positioning mounting brackets, as essential components connecting the encoder body to the equipment, are of paramount importance in their structural design.

[0003] Currently, common encoder mounting brackets typically use bolts or snap-fit ​​connections to connect the encoder body to the equipment. Taking bolt fastening as an example, during installation, workers need to use screwdrivers and other tools to tighten multiple bolts sequentially, which is not only cumbersome but also requires a certain level of skill from the installers. Disassembly also requires unscrewing each bolt individually, making the entire process time-consuming. While snap-fit ​​connections simplify operation to some extent, they often suffer from insufficient stability. During equipment operation, vibrations or external impacts can easily cause the snaps to loosen or even detach, leading to encoder instability. The root cause is that existing mounting bracket structures lack efficient quick-connect and limiting designs, failing to form an integrated and convenient installation and disassembly mechanism. For example, they lack structures that allow for quick and tight fitting through rotating parts, and there are no effective limiting structures to prevent loosening or detachment of connecting parts after installation. This results in complex, inefficient, and unstable operations during encoder installation, maintenance, and replacement, failing to meet the demands of modern industrial production for efficient equipment maintenance and stable operation. Therefore, this utility model provides a multi-axis positioning mounting bracket for encoders to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a multi-axis positioning mounting bracket for encoders to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-axis positioning mounting bracket for an encoder includes an encoder body and a fixed bracket mounted on a housing for connecting with the encoder body. Two support brackets for assembling with the fixed bracket are symmetrically fixedly connected to the housing of the encoder body. Each support bracket has two first connecting holes at its end furthest from the encoder body. A second connecting hole is provided on the fixed bracket corresponding to the first connecting holes on the support brackets. A connecting post for assembling the fixed bracket and support brackets is rotatably connected inside the first connecting hole. Two limiting rods are symmetrically connected to the outer wall of the connecting post near the fixed bracket. An adjustment mechanism is provided on the connecting post for adjusting its position to control the tight fit between the fixed bracket and support brackets. An auxiliary mechanism for adjusting the rotation of the connecting post is provided inside the first connecting hole.

[0007] As a further embodiment of this utility model, the adjusting mechanism includes a fixed ring, a top ring, a limiting block, and a limiting groove. Both ends of the connecting column extend through the interior of the first connecting hole to the outside of the first connecting hole. A fixed ring is fixedly connected to the outer wall of the end of the connecting column away from the fixing frame. A top ring is movably sleeved on the connecting column. A limiting groove is formed on the outer wall of the connecting column facing the top ring. A gear groove is formed on the inner wall of the limiting groove. A limiting block is fixedly connected to the inner wall of the top ring at the position corresponding to the limiting groove. The limiting block meshes with the gear groove inside the limiting groove, and the limiting block itself is elastic.

[0008] As a further embodiment of this utility model, both the fixing ring and the top ring are cylindrical structures, and the top ring is located between the fixing ring and the support frame. The side walls of the fixing ring and the top ring that are close to each other have a continuous sinusoidal curve in cross-sectional profile, and the fixing ring and the top ring are interlocked together.

[0009] As a further embodiment of this utility model, the adjustment mechanism includes a connecting groove, a T-shaped slide groove, a slider, and a spring. Two connecting grooves are symmetrically opened inside the first connecting hole. T-shaped slide grooves are opened on the inner wall of both connecting grooves. Sliders are movably engaged inside both connecting grooves through the T-shaped slide grooves. Springs are fixedly connected to the clockwise side wall of both T-shaped slide grooves. The free end of the spring is fixedly connected to the side wall adjacent to the corresponding slider.

[0010] As a further embodiment of this utility model, a connecting block is fixedly connected to the outer wall surface of the connecting column at the position corresponding to the connecting groove. The end of the connecting block away from the connecting column extends into the interior of the corresponding connecting groove, and the connecting block is located on the counterclockwise side of the slider.

[0011] As a further embodiment of this utility model, two through holes are symmetrically opened inside the second connecting hole. The shape and size of the structure formed by the through holes and the second connecting hole are adapted to the shape and size of the structure formed by the connecting column and the limiting rod. On the side wall of the fixing bracket away from the encoder body, two slots are symmetrically opened with the second connecting hole as the center, and the two slots are offset from the corresponding two through holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a support frame, a fixed frame, a connecting column, a limiting rod, a fixing ring, a top ring, a limiting block, and a limiting groove, allows for the assembly of the fixed frame and the support frame. By rotating the top ring with a tool, the connecting column moves in conjunction with the sinusoidal curve of the fixed ring and the top ring's wall surface. Combined with the limiting rod's positioning, this achieves a tight fit between the fixed frame and the support frame. Reversing the rotation of the top ring allows for disassembly. This solves the problems of complex installation and disassembly, low efficiency, and inconvenience for encoder body replacement and maintenance associated with existing encoder mounting brackets.

[0014] 2. This utility model utilizes a structure including a first connecting hole, a connecting groove, a T-shaped slide, a slider, a spring, a connecting block, a second connecting hole, a through hole, and a retaining groove. When the connecting post passes through the second connecting hole, rotating the connecting post clockwise aligns the limiting rod with the through hole. The connecting block pushes the slider, causing the spring to deform. After release, the spring returns to its original position, driving the connecting post to rotate, thus misaligning the limiting rod with the through hole. The retaining groove then limits the positioning of the limiting rod. This solves the problem of inaccurate positioning and easy rotation and detachment of the connecting post during the initial installation of the existing encoder mounting bracket, leading to unstable installation.

[0015] 3. In this invention, the elastic limiting block engages with the limiting groove, preventing the top ring from rotating slightly due to vibration when the equipment is subjected to vibration or external impact. This solves the problem that existing encoder mounting brackets are prone to loosening of connecting parts under complex working conditions, affecting equipment stability.

[0016] 4. In this invention, the sinusoidal curve-shaped wall surface where the fixed ring and the top ring are close to each other allows for precise fine-tuning of the fit between the fixed frame and the support frame by slightly rotating the top ring. This solves the problem that existing encoder mounting brackets cannot meet different installation accuracy requirements and lack sufficient installation accuracy. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8In this embodiment of the invention, a multi-axis positioning mounting bracket for an encoder includes an encoder body 1 and a mounting bracket 2 installed on a housing for connecting the encoder body 1. Two support brackets 3 are symmetrically fixedly connected to the housing of the encoder body 1 for assembly with the mounting bracket 2. In use, the encoder body 1 is connected to the corresponding equipment by splicing the two support brackets 3 with the mounting bracket 2. Two first connecting holes 4 are provided on the end of each support bracket 3 away from the encoder body 1. The number of first connecting holes 4 can be determined according to actual usage and is not limited here. A second connecting hole 16 is provided on the mounting bracket 2 at the position corresponding to the first connecting holes 4 on the support brackets 3. The number of second connecting holes 16 is the same as the number of first connecting holes 4. The interior of each first connecting hole 4 is rotatably connected to a device for connecting the mounting bracket 2 to the... The connecting column 5, which is spliced ​​with the support frame 3, is cylindrical. Two limiting rods 10 are symmetrically connected to the outer wall of the end of the connecting column 5 near the fixed frame 2. The end of the connecting column 5 near the fixed frame 2 and the corresponding two limiting rods 10 form a cross-shaped structure. When the fixed frame 2 and the support frame 3 are assembled together, the cross-shaped structure of the limiting rods 10 formed by the connecting column 5 and the limiting rods 10 can play a limiting role in the position of the connecting column 5, preventing the connecting column 5 from separating from the interior of the corresponding second connecting hole 16 on the fixed frame 2 during use, which would cause the fixed frame 2 and the support frame 3 to be unable to be stably fixed together. The connecting column 5 is provided with an adjustment mechanism for adjusting the position of the connecting column 5 and thus controlling the fixed frame 2 and the support frame 3 to fit tightly together. The interior of the first connecting hole 4 is provided with an auxiliary mechanism for adjusting the rotation of the connecting column 5.

[0028] The adjustment mechanism includes a fixed ring 6, a top ring 7, a limiting block 8, and a limiting groove 9. Both ends of the connecting column 5 extend through the interior of the first connecting hole 4 to the outside of the first connecting hole 4. The fixed ring 6 is fixedly connected to the outer wall of the end of the connecting column 5 away from the fixing frame 2. The top ring 7 is movably sleeved on the connecting column 5. A limiting groove 9 is opened on the outer wall of the connecting column 5 at the position of the top ring 7. A gear groove is opened on the inner wall of the limiting groove 9. A limiting block 8 is fixedly connected to the inner wall of the top ring 7 at the position corresponding to the limiting groove 9. The limiting block 8 meshes with the gear groove inside the limiting groove 9, and the limiting block 8 itself is elastic.

[0029] Both the fixing ring 6 and the top ring 7 are cylindrical structures, with the top ring 7 located between the fixing ring 6 and the support frame 3. The side wall of the top ring 7 away from the fixing ring 6 contacts the adjacent side wall of the support frame 3. The side walls of the fixing ring 6 and the top ring 7 that are close to each other both have a continuous sinusoidal curve cross-sectional profile, and the fixing ring 6 and the top ring 7 are interlocked. The outer wall of the top ring 7 has two symmetrically formed clamping grooves, such as... Figure 5 As shown.

[0030] In use, first assemble the fixed frame 2 with the two support frames 3, ensuring that the connecting post 5 inside the first connecting hole 4 on the support frame 3 passes through the corresponding second connecting hole 16 on the fixed frame 2, and that the limiting rod 10 is located in front of the fixed frame 2. At this time, the operator can use tools such as pliers to clamp the top ring 7 in the two clamping slots to drive the top ring 7 to rotate on the connecting post 5. Since the side walls of the fixed ring 6 and the top ring 7 that are close to each other are both in the shape of a continuous sine curve, and the side wall of the top ring 7 away from the fixed ring 6 is in contact with the side wall of the support frame 3 adjacent to it, as the top ring 7 rotates, the fixed ring 6 will move the connecting post 5 away from the top ring 7. Under the limiting action of the positioning rod 10, the fixed frame 2 and the support frame 3 can be tightly fitted together to achieve the effect of quick assembly. At the same time, when the top ring 7 rotates, the limiting block 8 will deform due to the influence of external force and move inside the limiting groove 9 with the movement of the top ring 7. When the top ring 7 cannot rotate, the limiting block 8 will restore its deformation and mesh with the corresponding gear groove inside the limiting groove 9 again, thereby achieving the effect of limiting the top ring 7 so that it cannot rotate on its own without the action of external force. Similarly, when it is necessary to remove the encoder body 1 for replacement and maintenance, simply rotate the top ring 7 in the opposite direction to reset it. The operation is simple and can complete the quick installation and disassembly of the fixed frame 2 and the support frame 3, thus facilitating the replacement and maintenance of the corresponding encoder body 1.

[0031] The adjustment mechanism includes a connecting groove 11, a T-shaped slide 12, a slider 13, and a spring 14. Two connecting grooves 11 are symmetrically opened inside the first connecting hole 4. The inner wall of each connecting groove 11 is provided with a T-shaped slide 12. The slider 13 is movably engaged inside each connecting groove 11 through the T-shaped slide 12. The clockwise side wall of each T-shaped slide 12 is fixedly connected to a spring 14. The free end of the spring 14 is fixedly connected to the side wall adjacent to the corresponding slider 13.

[0032] A connecting block 15 is fixedly connected to the outer wall of the connecting post 5 at the position corresponding to the connecting groove 11. The end of the connecting block 15 away from the connecting post 5 extends into the interior of the corresponding connecting groove 11, and the connecting block 15 is located on the counterclockwise side of the slider 13.

[0033] If the connecting post 5 rotates clockwise inside the first connecting hole 4, the connecting block 15 will push the slider 13 to slide clockwise inside the connecting groove 11, at which time the spring 14 will be deformed by force.

[0034] Two through holes 17 are symmetrically formed inside the second connecting hole 16. The shape and size of the structure formed by the through holes 17 and the second connecting hole 16 are adapted to the shape and size of the structure formed by the connecting post 5 and the limiting rod 10, such as... Figure 2As shown, in the initial state, the positions of the two limiting rods 10 on the connecting post 5 and the two through holes 17 on the second connecting hole 16 are misaligned. Therefore, when the connecting post 5 is passed through the interior of the second connecting hole 16, the connecting post 5 needs to be rotated 90 degrees clockwise to adjust the position of the upper limiting rod 10 on the connecting post 5 to the corresponding position of the through hole 17 on the second connecting hole 16. Only then can the connecting post 5 and the limiting rod 10 be passed through the interior of the second connecting hole 16 and the corresponding through hole 17. On the side wall of the fixing bracket 2 away from the encoder body 1, there are two slots 18 symmetrically opened with the second connecting hole 16 as the center, and the two slots 18 are misaligned with the two corresponding through holes 17.

[0035] When the connecting post 5 needs to be passed through the corresponding second connecting hole 16 during use, the operator can rotate the connecting post 5 clockwise so that the position of the upper limit rod 10 corresponds to the position of the through hole 17 on the corresponding second connecting hole 16, and then insert the connecting post 5 into the corresponding second connecting hole 16. At this time, the spring 14 is deformed by force. Then, the connecting post 5 is released when the end of the connecting post 5 away from the support frame 3 extends to the front of the fixed frame 2 and the limit rod 10 also extends to the front of the fixed frame 2 through the corresponding through hole 17. At this time, the spring 14 returns to its deformation and drives the connecting post 5 to rotate counterclockwise to reset, so that the positions of the two limit rods 10 and the two through holes 17 are misaligned again. As a result, the connecting post 5 cannot be removed from the interior of the second connecting hole 16 under the influence of the limit rod 10, thereby achieving the effect of initially snapping the fixed frame 2 and the support frame 3 together, which is convenient for the fixed frame 2 and the support frame 3 to be tightly fixed together by the adjustment mechanism later.

[0036] By using two slots 18 on the outside of the second connecting hole 16, when the limiting rod 10 is in the front position of the fixing frame 2 during use, the slots 18 can limit the position of the two limiting rods 10, so that the connecting column 5 cannot rotate. This avoids the problem that the connecting column 5 will rotate due to the influence of the fixing ring 6 when the top ring 7 rotates, causing the equipment to malfunction.

[0037] The working principle of this utility model is as follows:

[0038] In use, first assemble the fixed frame 2 with the two support frames 3, ensuring that the connecting post 5 inside the first connecting hole 4 on the support frame 3 passes through the corresponding second connecting hole 16 on the fixed frame 2, and that the limiting rod 10 is located in front of the fixed frame 2. At this time, the operator can use tools such as pliers to clamp the top ring 7 in the two clamping slots to drive the top ring 7 to rotate on the connecting post 5. Since the side walls of the fixed ring 6 and the top ring 7 that are close to each other are both in the shape of a continuous sine curve, and the side wall of the top ring 7 away from the fixed ring 6 is in contact with the side wall of the support frame 3 adjacent to it, as the top ring 7 rotates, the fixed ring 6 will move the connecting post 5 away from the top ring 7. Under the limiting action of the positioning rod 10, the fixed frame 2 and the support frame 3 can be tightly fitted together to achieve the effect of quick assembly. At the same time, when the top ring 7 rotates, the limiting block 8 will deform due to the influence of external force and move inside the limiting groove 9 with the movement of the top ring 7. When the top ring 7 cannot rotate, the limiting block 8 will restore its deformation and mesh with the corresponding gear groove inside the limiting groove 9 again, thereby achieving the effect of limiting the top ring 7 so that it cannot rotate on its own without the action of external force. Similarly, when it is necessary to remove the encoder body 1 for replacement and maintenance, simply rotate the top ring 7 in the opposite direction to reset it. The operation is simple and can complete the quick installation and disassembly of the fixed frame 2 and the support frame 3, thus facilitating the replacement and maintenance of the corresponding encoder body 1.

[0039] When the connecting post 5 needs to be passed through the corresponding second connecting hole 16 during use, the operator can rotate the connecting post 5 clockwise so that the position of the upper limit rod 10 corresponds to the position of the through hole 17 on the corresponding second connecting hole 16, and then insert the connecting post 5 into the corresponding second connecting hole 16. At this time, the spring 14 is deformed by force. Then, the connecting post 5 is released when the end of the connecting post 5 away from the support frame 3 extends to the front of the fixed frame 2 and the limit rod 10 also extends through the corresponding through hole 17 to the front of the fixed frame 2. At this time, the spring 14 returns to its deformation and drives the connecting post 5 to rotate counterclockwise to reset, so that the positions of the two limit rods 10 and the two through holes 17 are misaligned again. As a result, the connecting post 5 cannot be removed from the interior of the second connecting hole 16 under the influence of the limit rod 10, thereby achieving the effect of initially locking the fixed frame 2 and the support frame 3 together, which is convenient for the subsequent adjustment mechanism to tightly fix the fixed frame 2 and the support frame 3 together.

[0040] By using two slots 18 on the outside of the second connecting hole 16, when the limiting rod 10 is in the front position of the fixing frame 2 during use, the slots 18 can limit the position of the two limiting rods 10, so that the connecting column 5 cannot rotate. This avoids the problem that the connecting column 5 will rotate due to the influence of the fixing ring 6 when the top ring 7 rotates, causing the equipment to malfunction.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
